Patent CA-2250797-A1 (CA)
Title: Static partial order reduction
Inventor: PELED DORON A
IPC: G06F11/36
Filed: 1998-10-21
Abstract: A static partial order reduction generator and process result in a substantiallyreduced state space graph of a multi-process system, independently of the model checking process. The process of this invention creates a modified state graph generator with appended rules that allow any desired state searching tactic (breadth first, depth first, etc.) to be employed when states and transitions are considered in the course of verification. This permits use of existing model checking tools without needing to modify them. The static partial order reduction is made possible by realizing that a prior art condition that at least one state along each cycle of the reduced state graph must be fully expanded can be guaranteed by considering the individual processes that make up the system and identifying certain transitions in those processes.

Patent CA-2261922-A1 (CA)
Title: Molecular modelling of neurotrophin-receptor binding
Inventor: SHAMOVSKY IGOR L
IPC: G16B15/30
Filed: 1997-07-31
Abstract: The present invention relates to a computational method for identifying the bioactive conformations of peptide domains, in particular, the geometries of complexes of neurotrophins and their receptors. The bioactive conformation of the Nerve Growth Factor (NGF) amino and carboxyl termini (Trk binding domain) was determined. The complex of the NGF termini splits into two distinct regions: a rigid region (residues 9-11 and 112'-118') and a flexible loop (residues 1-8). The geometry of the rigid region, which is maintained by electrostatic interaction between Glu11 and Arg118', is conserved in active molecules only. The separation of the flexible loop from the rigid region is necessary in order to eliminate an influence of the loop on the biologically active conformation of the rigid region. The present invention also relates to a method for identifying and theoretically modelling specific receptor binding sites for Nerve Growth Factor (NGF) and Brain-Derived Neurotrophic Factor (BDNF) on their receptors, TrkA and TrkB, respectively. The present invention also relates to a method for identifying and theoretically modelling a receptor binding site for neurotrophins, such as NGF, BDNF, NT-3, and NT-4/5, of the common neurotrophin receptor p75NTR.

Title: Phage bonded to nuclear location signal
Inventor: HASEGAWA MAMORU
IPC: C12N15/87
Filed: 1996-12-27
Abstract: A .lambda. phage having a nuclear location signal imparted thereto has been obtained by constructing a vector capable of expressing a fused protein composed of a gpD protein constituting the head of a .lambda. phage with a nuclear location signal sequence, transforming Escherichia coli by this vector and, further, propagating a mutant .lambda. phage which cannot express the gpD protein in E. coli in this transformant. It has been confirmed that the obtained .lambda. phage is capable of packaging .lambda. phage DNAs of 80 % and 100 % in genome size. After further confirming that the nuclear location signal is exposed to the outside from the head of this phage, this phage has been micro-injected into cells to analyze its location activity toward the nuclei. Thus it has been clarified that this phage has a location activity toward nuclei.

Abstract: A method for reducing brightness reversion and yellowness (b*) of a bleached mechanical wood pulp is described. The pulp is digested in an aqueous formaldehyde solution containing carbonate, preferably magnesium or calcium carbonate, preferably in an amount up to 30 % by weight of pulp and at a temperature in the range of 15 to 60 ~C. Paper made from the digested pulp can be further improved by treating with a reversion inhibitor such as a polyethylene glycol bisthiol.

The aqueous hydrogen peroxide solution preferably contains magnesium or calcium carbonate. This bleaching method can be coupled with the formaldehyde/carbonate treatment to produce bleached hardwood or softwood mechanical pulps with reduced reversion properties and improved b* characteristics.

Title: Static electrification assisted dielectrokinesis detection of plastics and other materials
Inventor: AFILANI THOMAS
IPC: G01N27/60
Filed: 1998-04-16
Abstract: A dielectrokinesis detector includes a chamber housing an exact dielectric replicate reference material that is subjected to external static electrification. The reference material is mechanically constrained, enabling the detection of the polarization energy dynamics of constrained dielectrophoretic force indicating the presence of any target with dielectric properties identical to the properties of the reference material. An antenna assembly increases the proximity distance (range) of detection. The static electrification source for the reference material increases the longevity of the detection ability to provide continuous detection capability, and an external electronic circuit source of electrical energy via an electrical current surge gives a quantifiable manifestation of the detection. In accordance with the principals of dielectrophoresis, the detector can detect the presence of a specific material irrespective of the presence or absence of any type of intervening, visual obstructing material structures, barriers or electromagnetic interference (EMI) signals.

Inventor: PHIPPS JONATHAN STUART
IPC: D21H11/00
Filed: 1998-07-10
Abstract: A new composite material which is useful as a pigment in paper making or paper coating is described. The new material is produced by precipitating a white insoluble pigment compound, e.g. calcium carbonate, in an aqueous suspension containing fine particulate material preferably at least part of which is fresh, i.e. previously unused, e.g. titanium dioxide particles, and fibres, e.g. cellulosic fires. These may be derived from separate stocks and added together to produce the composite pigment material. The new material comprises a bonded matrix of the fibres and the white pigment compound having particles of the fine particulate material, e.g. TiO2, dispersed and bonded within the matrix. The new material may itself exist as particles in dry or wet form which may be further treated in a known way prior to use in paper making or paper coating. Use of the new material allows expensive fine particulate material such as TiO2 particles to be better retained in a paper making composition whilst at the same time avoiding the problem of agglomeration or "crowding" of the fine particles which in the prior art is known to affect adversely the optical properties of the composition produced using the fine particles.
